ENGINE BED.

To all whom it may concern:

Be it known that I, ARTHUR W. (hrs, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Engine Beds; and I do declare the following to be a full, clear, and exact description'of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and t0 the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to engine beds and particularly to a bed adapted to be secured to a portable mechanism whereby the engine which furnishes the power for operating the mechanism may be convenientlytransported along with it.

designed to provide for the added weight and vibration of an explosion engine, the advantages resulting from the application of anexplosion motor upon the superstructure would, in a measure, be negatived unless some rovision was made for a 1 m 3 :1

the engine bed or support to 'a part of the harvester frame best adapted to withstand the strain due to the weightand vibration of the motor. It has been proposed heretofore to apply explosion motors to the frame of existing harvesters for the purpose of imparting motion to the operating mechanism thereof but in such cases the engine has generally beensupported from the superstructure'bymeans of stay rods, struts and the like, with'the result that there is a tendency to loosen the parts of the superstructure due to the Weight and vibration of the motor.

Specification of Letters Patent. Patented Mar. 28, 1922. Application filed-June 16, 1919. Serial No. 304,404.

I have provided means whereby the objections above enumerated will, in a considerable measure, be eliminated and I have so constructed the bed that it is not only easily applied and removed without the necessity of drilling holes or otherwise changing any of the parts of the harvester, but I have also rigidly attached to the rear members of the harvester frame at the point where there is theleast liability of vibration and in convenient proximity to the normal drive shaft of the harvester.

I have also provided means whereby the engine may be adjusted upon its bed within certain limits to compensate for various types of harvesters so that a standard type of'bed will sufficefor different types of ma chines and I have provided means for efficient clearance for the power transmitting means which connects the drive shaft of the engine to the drive shaft of the harvester.

In the drawings,

Fig; I is a partial perspective view of a known type of harvester to which my invention is applied.

Fig. II is a fragmentary perspective view of a rear portion of the main frame of a harvester, showing the engine base in position.

Fig. III is a fragmentary perspective view of a portion of the base and a clamp frame of a harvester, here shown as including a rectangular structure consisting of the longitudinal side bars 2 and 3 and the transverse end bars 4 and 5. The end bars "4: and 5 support a drive shaft 6' journaled in bearing 7 and 8 and driven by suitable means through a sprocket wheel 9, the shaft 6 in turn communicating motion to the operating parts of the harvester as, for example, through the medium of the sprocket 9'. The construction thus far described, except for the sprocket 9, is common to known types of harvesters andthe constructed the device so'that it may be i frame consisting of the parts 2 to 5 inclusive is known as. the rear part of the main frame of the harvester.

By reference to Figs. I, II and IV it will be apparent that I have provided an engine bed which may be conveniently attached to the rear cross members of the main harvester frame so that the weight of the engine or power unit is carried entirely by the main frame, thus ellminating the necessity for placing strain upon the superstructure, which is the part of the harvester least capable of sustaining it.

In carrying out my invention I provide an engine bed, here shown as consisting of a substantially rectangular frame 10, provided with frame-engaging bracket arms 11 and 12 which are adapted to be secured to the main frame by suitable mechanism without marring the harvester frame. The engine bed is shown as provided with elongated slots 13, 1 1, 15 and 16 to which the power unit or engine 17 may be suitably clamped by fastening devices 18, which may consist of clamp bolts adjustable in said slots so that the position of the engine on the frame may be adjusted within limits dependent upon the lengths of the slots. The clamping arm 11 is provided with an elongated slot 19 in which is secured a clamping hook 20, the hook portion 21 of which is adapted to engage the lower edge of the rear end bar 5- so that when the nut 22 is screwed upon the threaded end 23 of the clamp 20, the washer 24 in conjunction with the end 21 will clamp the parts together. The end of the bracket arm 12 is fastened to a supporting beam 25 of channel form by the bolts 26 and 27which pass on the respective sides of the bar 5, the heads of which abut against the under side of the web of the beam 25 and the outer ends of which receive nuts 28 and 29 whereby the bracket arm 12, the bar 5 and the beam 25 are secured together. One end of the beam 25 is fastened to the bar 3 by a clamping member 30 while the opposite end 31' of the beam supports the outer endof the frame 10, there being a block 32 between the web of the beam 25 and the end bar of the frame 10, the height of the block corresponding to the width of the bar 5 so that when all of the parts are'in place, as shown in Fig. II, a rigid, symmetrical structure will be provided. I

By reference to Fig. II it will be observed that the beam 25, which provides rigidity between theharvester frame and the engine bed, is set at an acute angle with respect to the bar 3 and, in conjunction with the bar3 and bar 5, providesa supporting .frame substantially in-the form of a right angled trianglefor the bed 10 so that both the bars?) and 5 will support their proportionof the weight of the engine. It will also be observed that the bracket arm 12 is offset with respect to the bed 10 so as to provide a clearance space 33 for the transm1ssion chain 3 1, which communicates motion from the sprocket 35 on the engine shaft to the sprocket 9 on the drive shaft 6 of the harvester. The arms 11 and 12 may be connected by a bar 36 if desired, and I have therefore, shown the bar 36 as integral with the arms 11 and 12 which, in turn, are shown as integral with the engine bed so that the whole may be cast in a unitary structure.

If it is desired to shift the engine bed slightly about the pivot 37, the clamp 20 can be loosened and the nuts 28 and 29, as well as the clamp 30, may be loosened to shift the bed, the shifting being possible on account of the elongated slot 19. If the engine only is to be shifted on the bed, the clamping bolts 18 may be loosened for this purpose. a

It will be apparent from the foregoing that the engine bed may be expeditiously and conveniently attached to the main frame of a harvester in close proximity to the drive shaft and supported at the-most convenient point on the harvester frame and that the same may be accomplished without the necessity of employing special tools or any special skill in either attaching the bed to the harvester frame or detaching it there from, and that liability of damage to the harvester frame due to vibration or the weight of the engine will be materially reduced if not wholly eliminated. i
